They were crammed in a closet.
Trapped with a spider.
"Are you sure that…" Parvati managed out.
Lavender put her hand over her mouth, "Don't speak. It senses fear."
She looked at her, as if to say, "We're bloody Gryffindors and we can't handle a measly spider?"
Lavender seemed to understand the silent question, because she pursed her lips, "Fine. Just kill it."
Unfortunately, the closet was very small and moving without hitting or kicking each other turned out to be difficult.
"Stop moving!"
"You told me to kill it."
"Parvati!"
"What, Lavender?"
Lavender's voice was merely a shaky breath as she pointed at the brunette's shoulder, seemingly forgetting how to breathe.
The pair stilled, suddenly, hearing a set of footsteps approaching the closet.
A blinding light entered the closet and the girls unsuccessfully attempted to blink away the sudden light.
"Miss Brown, Miss Patil, what are you two doing in the broom closet?"
"Sp-sp-spider..." the blonde stuttered, pointing at the creature on Parvati's shoulder.
"My goodness!" Professor McGonagall frowned, stepping towards the girl, flicking the spider away, "Get back to class."
Needless to say, the girls scurried away like spiders quite quickly...
